London, UK

Flatpay is one of Europe's fastest-growing fintech companies, now expanding across the UK.

The role

As an Inside Sales Team Lead you own the output of a team of Inside Sales Representatives. That means driving sales volume and quality, managing the full sales cycle from signature through to customer onboarding, and making sure your team hits its numbers consistently. Your own sales track record is what gives you credibility here. But the job itself is about leading, coaching, and running your floor well.

What you'll do

  • Set the standard for effort and results, and run the daily rhythm that converts activity into signed sales and completed onboardings

  • Diagnose whether an ISR's gap is volume, product knowledge, or quality, and coach accordingly using call reviews, roleplay, shadowing, and 1:1s

  • Bring performance data into coaching conversations, and recognise people for effort, improvement, and culture, not only for hitting numbers

  • Keep morale and motivation up in a high-rejection environment, and run onboarding that gets new hires to their first sale faster

  • Review sales and activity metrics on a set cadence, catch dips before they show up in the monthly result, and hold reps accountable across the full onboarding cycle

  • Give your manager an accurate read on performance, lead with what matters most, and bring a proposed solution alongside any problem

  • Interview every ISR who joins your team using the methodologies we use at Flatpay

What we're looking for

  • A strong track record in a sales role, ideally telesales or another high-volume, high-rejection environment

  • Experience coaching or mentoring colleagues, whether formally as a team lead or informally as a senior rep

  • Comfort working with performance data: you can read a set of team numbers and make a call based on what they show

  • Willingness to have direct performance and behaviour conversations, and to follow through on them

  • Consistency: you hold the same standard whether or not a manager is watching

Previous management experience is not required. We promote strong ISRs into this role and support them through it.

Our values

  • Happy Humans: the energy you bring sets the tone for your whole team's day

  • No Assholes: we hire good people and expect everyone to be treated with respect, colleagues and customers alike

  • It's Our Business, Own It: your team's performance and behaviour are yours to own

  • Start With No: challenge your own read on a struggling rep before acting on it

  • Sky-High Ambitions: the targets you set should stretch your best rep, not just your average one

  • The Best Argument Wins: if a rep has a better read on their own gaps than you do, take it

What's in it for you

  • Medicash EAP and Medicash Proactive health support

  • Bupa Select private healthcare

  • Refer-a-friend scheme: earn up to £500 for every successful referral

Background and requirements

  • Right to work in the UK without sponsorship

  • Based in London, fully office based 5 days per week
